I have about 300 mailboxes in a single database using Exchange 2010 SP1. I'd like to setup a new retention policy that deletes appointments and meetings older than two years from all Exchange mailboxes. Reoccurring appointments/meetings can be left alone if they are still current.
I see 15 different tag type options when setting up a new Retention Policy Tag, but I don't see "Calendar" as one of the options.
Is it still possible to delete calendar entries using a retention policy or some other mechanism? Manually running a Powershell command from time to time would be fine too.
